Answer 2

I can help you with your math problem. Here is the detailed solution:

a) -5ab(3a^2 - 0.2b^2 + ab) = -15a^3b + a^2b^2 + 5ab^3

б) (a + 4)(a - 5) = a^2 - a - 20

B) (35a^3b - 28a^4) : 7a^3 = 5b - 4a

The final expression in the standard form is:

-4a - 15a^3b + a^2b^2 + 5ab^3 + a^2 - a - 20 + 5b

You can simplify it by combining the like terms:

-4a - a + a^2 - 20 + 5b - 15a^3b + a^2b^2 + 5ab^3

= a^2 - 5a - 15 + 5b - 15a^3b + a^2b^2 + 5ab^3

I hope this helps. You can learn more about polynomials and their standard form from [this website](https://math-prosto.ru/ru/pages/polynomials/polynomial_standard_form/).
